Grubb then put his hand over the camera lens, and he and another crewman covered Grubb’s computer screen with their hands.

The reaction led to fans asking on Twitter what Grubb and his team did not want fans and TV viewers to see on his computer screen. Was he attempting to hide some sort of secret data he didn’t want the world to see?

Grubb isn’t a big tweeter—his Twitter profile shows 17 tweets since he opened the account in July.

So either he had heard about the comments on Twitter or he was checking Twitter to see if Hamlin had guaranteed another victory for an upcoming race. (Hamlin predicted on Twitter he would win Sunday’s race.)

Grubb explained that what was on his computer screen was private information and tried to have some fun with fans who might believe differently.
